super users and accounts ,and xf86config- i have a few question


I understend that the root is "God" on linux ther are no limits for root.
how can i setup a similar user on Slackware 9.1 - superuser.
that has access to everything and changing stuff like root
is that possible?
what does the nummbers and user groups stand for i don't understand that.

yes about xf86config
i have documatation of my monitor that sasy this
horizonatal freq.
31.5-68.7 KHz
vertical freq
60-85 Hz
resolutions supported
800×600 85Hz
1024×768 85Hz
1152×864 75Hz
1280×1024 60Hz
when i enter the manul refresh rates(freq) in xf86config
and default resolution 1024×768 (change modes)
it asks do i wont virtual desktop that is larger then phisical
i answer with "n"
but when i start x server
with resolution 1024×768, virtual desktop is larger then phisical and it's getting on my nervs.
then from the KDE (3.1) in control center there is somthing to set up monitor and graphic card
when i enter there my freq. and graphic card
after restarting X it brings up with 1024×768 Vert.85Hz, Hor. 70KHz
and on my monitor it's a costume mode.
after ctrl+alt+ "+" it switchs to 1024×768 85Hz, 68.7KHz
i don't understand why does it won't start imidatly at 1024×768 85HZ, 68,7Khz???
P.S
why don't I get a 32bit prompt in xf86config my graphic card is Nvidia GeForce MX460 with 64MB DDR ram
i use also win XP and there is only 32bit and 16 bit
i also installed nvidia drivers and then try xf86config
nothing happend.

One question why the hell would you want another super user? or root user?
If your thinking about giving yourself "super powers" think again

1) Your user happends to damage the system its alot harder to fix it this is why users dont have this power.

2) A virus or worm gets on that machine and now that worm has full access to that system...

3) Someone hacks you and spawns a terminal from your account now they have full access to your whole system.

4) Some programs will not run as root or super user.

yes i read somwherwe on this forum how to set up login from kde


change inittab's default runlevel to 4. its location is /etc/inittab heres what you want
# These are the default runlevels in Slackware:
# 0 = halt
# 1 = single user mode
# 2 = unused (but configured the same as runlevel 3)
# 3 = multiuser mode (default Slackware runlevel)
# 4 = X11 with KDM/GDM/XDM (session managers)
# 5 = unused (but configured the same as runlevel 3)
# 6 = reboot

# Default runlevel. (Do not set to 0 or 6)
id:4:initdefault:


Well I did that and now, it sasy the starting up somthing black screen offcourse
and then it reboots it self
I don't have a login promt anymore

install a package named sudo, then edit /etc/sudoers and add a line to it:

username ALL=(ALL) ALL

the person with that username will have root's power.

this is how sudo works, you log in as a user, type in "sudo su", it will ask for the root's password, and you will have root's power, if you type in something like "sudo konqueror", it will ask for the root's password, and you will open a konqueror screen with full root's power, you can edit, delete, create, anything in the system.
